okay, i want to figure this shit out

theres, oil return, thats the nipple on the bottom side

oil feed, thats what i think its the banjo line off the side of the block

coolant feed, thats the larger banjo fitting up the block towards the head

and coolant return!?! people said the back of the block. I CANT FIND THAT LINE

but, could i just tap into my upper rad hose neck? yes no? just put a fitting into it?

or is there a more reasonable place i can do it? i like it there. but i dunno if that will work,

i dunno, is there supposed to be a specific path/direction of the coolant flow?

na dude i wouldnt run it in the upper hose... that coolant return hole is back there somewhere.. iirc you just have to give it the reacharound to gain access.

i looked, and looked. anyone have a pic, of where it is?

why cant i just cap that off and sue the rad hose? its easy to get too

the only thing i would worry about is if it would prevent coolant flow. if coolant is being pushed through that rad hose, and through that coolant feed line, there would be no pressure differential, thus no flow. but it might work..

well the coolant goes  from the pass side t stat through the rad to the drivers side

so i could just angle the tube diagonal into the coolant neck..

that piece is not back there. is that part of the heater core line assembly?? is that why mine is missing, because im just running a U back to back for the heater core

The coolant return line goes on the same neck near the elbow by the head on the s14/s15 sr20. The s13 turbos were journal bearing t28's that were not liquid cooled. Just oil lines flowed through. That's why you didn't have that fitting on your s13 sr. Well done with the additional fitting!

I looked at my setup last night as I'm about to change over my old solid lines to Earls. Both oil line goes under the turbo not around the front like you have them, but that's up to you. The water feed on mine comes behind the motor from the heater circuit I presume. You could tee off from the loop you've made & have a nice dedicated supply to the turbo.

RAW: The Japaneese S13 red & black SR came with a T25, water & oil cooled. S14/S15 all came with T28 BB. Perhaps the US ones were different. Aussie S14/S15 turbos were T28 non-BB.
